SPECIFICATION forming part of Letters Patent No. 460,141, dated September 29, 1891.

Application filed December 8, 1890. Serial No. 373,898. (No model.) I

. To all whom it'may concern:

Be it known that I, HENRY KIRK, a citizen of the United States, residing at Minneapolis, county of Hennepin, and State of Minnesota, have invented certain new and useful Improvements in Hinges for Boxes or Orates,of which the following isa specification.

My invention relates to hinges having one wing adapted to be permanently secured to the lid of a box or other article, and another wing adapted to clasp a portion of the box itself; and the object of the invention is improvement of the hinge disclosed in my patent, No. 259,318, of June 13, 1882.

The improvements are illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the hinge. Fig. 2 shows the manner in which it is connected to a box. Fig. 3 is a side View, and Fig. 4 a top view, of the parts of the hinge disconnected. Figs. 5 and 6 show the sheetmetal blanks from which the two portions of the hinge are formed, and Fig. 7 shows the manner of applying the hinge to the box after the former has been attached to the lid.

In said drawings, 1 designates one of the wings of the hinge provided with holes 2 for receiving screws to attach it to the lid L of a box B or other article, as indicated in Fig. 2. The other wing is formed of a single sheetmetal piece having a fiat body portion 3 and another portion 4, bent therefrom, first at right angles, as shown at 5, and thence in inclined direction toward and past the end of the part The part 4 thus forms a spring that co-operates with the part 3 to constitute a clasp for attaching the hinge to the upper edge of a box, as indicated by dotted lines in Fig. 2. The Wing 1 being permanently secured to the box-lid and the other wing being adapted only to clasp the side of the box, it will be understood that the lid, while being adapted to open by turning on the hinge, can be readily removed by lifting it. In connecting the lid to the box, after the hinge has been attached to the lid as described, the end of the wing 3 is placed against the outside of the back of the box near the top with the extended portion of the spring 4; projecting inward over the inner edge of the back, as shown in Fig. 7, and then the lid is pressed inward and downward, causing the clasp to engage the back. As will be apparent, the clasp of the hinge thus constructed can be easily forced to engagement with the box without first spreading the clasp by hand, and when seated the exterior member will lie flat against the box.

In the construction of the wings of the hinge two sheet-metal blanks 6 and '7 (preferably brass) are used. The blank 6 is slitted on the lines 8, and the ears 9 are then bent around to form the sockets 10 for the ends of the pivot-pin 11. The extended tongue 12 is bent at the inner ends of the slits to a right angle to the body 3 to form the part 5, and is again bent at 12 parallel to the body 3 and extended at an inclination toward the latterto form the spring 4:- The other wing is formed by bending the narrower portion of the blank 7 to form the socket or bearing 13 for the middle portion of the pivot-pin. As will be readily understood, these operations are capable of being performed by machinery, and the hinges can be thus made at slight cost.

Having described my invention, what I claim is- A hinge having one wing adapted to provide a bearing for the middle portion of a pivot-pin and another wing formed of a sin gle sheet-metal piece having ears bent to form bearings for the ends of the pivot-pin, and a tongue bent to form a spring adapted to cooperate with the body of the wing to constitute a clasp, substantially as set forth.

HENRY KIRK.
